Jupiter
the principal deity of the ancient Greeks and Romans. He was worshipped by them under various epithets. Barnabas was identified with this god by the Lycaonians (Acts 14:12), because he was of stately and commanding presence, as they supposed Jupiter to be. There was a temple dedicated to this god outside the gates of Lystra (14:13).
